has for an object to provide a to permit the ed conveyer of the character novel conveying member made of preformed units detachably anner to be capable of pivotal structure, whereby individual units or flights to be easily and conveniently assembled and replaced in such manner as to minimize the liability of parts becoming broken or detached and the actamination of the material becompanying con ing transported. A further and conveying unit for use in t With these general obj others as may h consists in the element hereina defined in the claims at cation.

In general, the present vide an improved convey ceived within the ho to pivotally and more specific object of the invention is to provide a novel and superior unitary he present conveyer. ects in view, and such ereinafter appear, the invention 0 onvey er and in the conveying fter described and particularly the hub at one det end of this specifiinvention aims to proer of the general type Reissue Patent No. 18,445,

ted together in a novel and 11 be described.

ts of the conveying member a preformed open structure end and having at rgement capable of being rellow hub of a succeeding unit achably connect the units totherein and capable of being moved therethrough to eflect the conveyance of fiowable solid material through the casing in a continuous stream in the manner described in the Redler reissue patent above referred to. The conveying member I2 is in accordance with the present invention made up of a plurality of individual detachably and pivotally connected units l4 each of open structure having integral tion to one another to permit the units to remain connected together in all working positions of the conveying element and to be completely detached from one another in a simple and convenient manner upon relative movement of the units into an abnormal position. Each unit l4 preferably comprises a rigid member l6 provided at one end with a hollow hub l8 and at the other end with an enlargement capable of being reccived within the hollow hub of a succeeding unit to pivotally and detachably connect the units together. As illustrated in the drawing, 8 is provided with an opening 2.?

unit with the interior of the wall of the hollow hub in which it is received. The opening 22 in the hollow hub is preferably constructed of such width with respect to the enlargement as to prevent the enlargement from passing outwardly through the opening until the adjacent units being detached have been pivotally moved into an The forward wall 23 of the hollow huh I 8 of each unit is further provided with an opening or slot 28 arranged to communicate with the transversely extended opening 22 and through which the rigid member "5 of the succeeding unit is permitted to pass to permit the required pivotal movement of the units during the passage of the conveying member around the usual sprockets at each end of the conveyer.

The rigid member I6 is also in accordance with the present invention further provided with an integral member 30 adapted to impart an open structure to the unit and for cooperation with a suflicient portion of the interior of the casing to effect transportation of the-material in a continuous stream therethrough, and this'integral member 30 may take various forms according to the use to which the conveyer is to be put, and various illustrative forms of the integral member 30 have been herein illustrated. In Fig. 1 the member 30 is illustrated as of U-shape and formed integrally as a part of each hollow hub [8. In Fig. 3 the member 30 is illustrated as formed integrally with the rigid member I6 at an intermediate point between the ends thereof and is therein illustrated as of general U- shape. of general H-shape with the hollow hub i8 formed as a part of the crossbar of the H. In Fig. 5 the integral member 30 is illustrated asbeing of general X-shape, in which the ends of the integral member are adapted to cooperate with the corners of the interior of the casing to effect the desired transportation of the material in a continuous stream. The hollow hub l8 may, as illustrated in Fig. 5, be formed as an integral part of theX member. In Figs. 6 and 7 the integral member is illustrated as formed of general rectangular and circular shape, respectively, and while a number of modified forms and shapes of the integral member have been herein illustrated, it is to be understood that the invention is not limited to any particular shape, but that various skeletonized forms may be utilized which are adapted for cooperation with a suflicient portion of the interior of the casing to effect transportation of the material in a continuous stream therethrough.

From the description thus far, it will be observed that the present conveyer possesses all of the advantages of the so-called cable type of open flight conveyer of. the prior art with none of the disadvantages. Experience has shown that in some instances and for some purposes liability exists for the flights to slip upon the cable and consequently to change the pitch between flights with consequent disability to travel around the sprockets. In addition, in short lengths of conveyers the excessive number of bends imposed upon the cable detracts materially from the life thereof. In most all cables utilized in conveyers of the character specified internal. lubrication has been found necessary in order to permit the cable to flex, and the liability of the lubricant working into food products being conveyed by the conveyer is completely eliminated by the present invention which can be operated dry.

While the preferred embodiments of the present invention have been herein illustrated and described, it will be understood that the invention may be embodied in other forms within the scope of the following claims.

Having thus described the invention, what is claimed is:

1. In a conveyer for conveying flowable solid material, a transporting member comprising a plurality of preformed units detachably connected together and each being provided with a flight,

each unit'comprising a centrally disposed connecting member provided at one end with a hollow hub and at the opposite end with an enlargement capable of being received within the hollow hub of the next succeeding unit to pivotally and detachably connect the units together when in a 1 normal position, said hollow hub having the in- In Fig. 4 the member 30 is illustrated as terior of its rear wall curved and provided with a vertical slot therein'for the reception of. said centrally disposed connecting member to permit vertical pivotal movement thereof, and being further provided with a transversely extended opening through which the aforesaid enlargement may pass into and from said hollow hub, the portions of said enlargement projecting from opposite sides of saidconnecting member having curved rear walls for cooperation with the curved rear walls of the interior of said hub.

2. In a conveyer for conveying flowable solid material, a transporting member comprising a plurality of, preformed units detachably connected together and each being provided with a flight, each unit comprising a centrally disposed connecting member provided at one end with a hollow hub and at the opposite end with an enlargement capable of being received within the hollow hub of the next succeeding unit to pivotally and detachably connect the units together when in a normal position, said hollow hub being provided with connected openings in the lateral surface thereof, one opening comprising a vertically arranged slot for thereception of and to permit vertical pivotal movement of said centrally disposed connecting member, and the second opening being transversely extended and arranged to permit said units to be detached by movement in a vertical direction'after having been pivotally .1:
